MEANS FOR FASTENING OBJECTS TO IRON BEAMS.

SPECIFICATION forming part of Letters Patent N 0. 359,310, dated March 15, 1887.

Application filed September 9, 1886. Serial No. 213,155. (No model.) Patented in Germany April 2, 1886, No. 37,019.

To all whom it may concern:

Be it known that I, CARL BERNHARD Ax'r,

- of the city of Ghemnitz, in the Kingdom of the clinching of the said nails in or after driving in the same. This method, however, offers little security, as the nails frequently bend over to the wrong side, or when driven in against an iron clinching-surface do not bend or clinch at or near the point, but in the middle, thus in many instances rendering the attachment illusory.

Figures 1 and 2 are two vertical sections representing my improved method of attachment.

According to my improved method it is not necessary that the nail n should be clinched over in the form of a hook or formed into a loop, the same being driven between the jaws of one or more sheet-iron or other suitable angles, b. The nail is grooved or provided with suitable annular or other recesses, ribs, teeth, or screw-threads, so that the jaws of the angles 1) will act as a system of pawls in the recesses of the said nail, and will firmly hold the same and prevent all retrograde motion or loosening of the attachment.

Having now described my said invention and witnesses.

CARL BERNHARD AXT. Witnesses:

WILLIAM B. MATTHES, OTTO THEUERKORN.
